These tall, bakery-style muffins are packed with chocolate chips and full of banana flavor. With domed golden tops and pockets of melted chocolate chips in every bite. The ripe bananas bring natural sweetness and a tender crumb, while the Greek yogurt adds a slight tang and rich texture. They're packed with flavour, easy to make, and totally satisfying, whether fresh from the oven or straight from the fridge the next day. Perfect for breakfast meal prep, kids’ snacks, and casual entertaining (serve warm with coffee).
Preheat your oven to 425°F. Line a muffin pan with 12 paper liners or generously grease the muffin cups with nonstick spray.
In a large mixing bowl, add the flour, dark brown sugar, granulated sugar, baking powder, baking soda, and salt. Whisk together until well combined.
Add the chocolate chips and stir them in. Set aside.
In a medium bowl, add the mashed bananas, oil, eggs, vanilla extract and Greek yogurt. Whisk until very smooth.
Pour the wet ingredients into the dry ingredients then fold together very gently using a spatula or spoon until just combined. Do not over mix. The batter will be thick and look lumpy, which is perfect.
Optional step: cover and chill the batter for 30 minutes (or overnight). On testing we found chilling thickened the batter and helped the muffins rise taller with improved texture.
When you’re ready to bake fill the muffin cups to the very top. You should be able to fill all 12 cups (see notes).
Bake at 425ºF for 10 minutes, then reduce the temperature to 350ºF (but do not open the oven door) and bake for a further 10-15 minutes or until the muffins are risen and golden brown. A toothpick inserted into the center will come out clean.
As soon as you remove the muffins from the oven, scatter over a few extra chocolate chips. Leave the muffins to cool in the pan for 5 minutes then transfer them to a wire rack to cool.
Notes
Reserve extra chips for the top: I press a few chocolate chips onto hot muffins right out of the oven—picture-perfect and extra chocolate on every bite.
Bake in the center rack for even browning; rotating only if your oven has hot spots (but not until the last 3–4 minutes).
Don’t overmix! Fold the batter just until no flour patches remain. Overmixing creates tough muffins—lumps are good!
Use very ripe bananas: I go for bananas with lots of freckles—sweeter, softer, and they mash smoother for an authentic banana-bread flavor.
Measure bananas by volume: Use measuring cups for mashed banana, not just “number of bananas,” since sizes vary.
Room temp ingredients: Start with room temperature eggs and yogurt for a smoother batter and better rise.
Chill the batter: If time allows, cover and chill for 30 minutes (or overnight). I noticed this really helps the muffins rise sky-high.
Storage & Freezing Tips
Store muffins at room temperature in an airtight container for up to 3 days.
Refrigerate them for up to 5 days.
These muffins freeze beautifully. Wrap each one individually and freeze for up to 2 months.
Defrost at room temperature or pop in the microwave for 30 seconds for that just-baked feel.
Frequently Asked Questions
Can I make these muffins dairy-free? Yes! Use your favorite dairy-free yogurt (like coconut or almond) and dairy-free chocolate chips. The texture is still fantastic.
Can I use whole wheat flour? Absolutely! I swap up to half the all-purpose flour with white whole wheat. It gives the muffins a nuttier flavor and a bit more fiber, but keeping some all-purpose flour helps them stay light.
Why start the oven at a high temperature? This little trick helps the muffins rise fast and tall with domed tops. The initial heat at 425°F creates rapid steam and oven spring for that bakery-style dome. After 10 minutes, dropping to 350°F finishes the bake without drying, creating a perfect crumb for the banana chocolate chip muffins. Don’t open the oven at the switch.
My muffins sank—what happened? Usually underbaking or too much leavening. Bake until a toothpick has only a few moist crumbs. Also, measure flour correctly (spoon/level) and avoid overmixing.
Can I reduce the sugar? You can cut total sugar by 2–4 tablespoons; texture stays good thanks to banana/yogurt. Flavor will be less sweet—add a few extra chips on top to compensate.
